Formation of Mixed Complexes of Cadmium(II) with Methyl Imino Diacetic Acid and Some Amino Acids at Dropping Mercury Electrode

Abstract

The present investigation describes the polarographic determination of the stability constant of binary and ternary metal complexes of Cd(II) with methyl imino diacetic acid and some amino acids (isoleucinate, valinate, citrullinate, threoninate and serinate) by the treatment of Schaap and McMasters. The reduction of all the complexes has been found to be reversible and diffusion controlled, involving two electrons. The statistical and electrochemical effects have been discussed by using these stability constants.
